Abstract: The present invention refers to synthetic, cyclic peptides containing a sequence of 13 L-amino acids in their primary structure which present anti-inflammatory and antiallergic activities, useful for the treatment of acute or chronic inflammation and/or allergies, being particularly useful for the treatment of acute or chronic allergic asthma. The invention also describes a pharmaceutical composition containing said peptides, its use and a method to treat or prevent acute and/or chronic inflammatory and/or allergic disorders.

Abstract: The present invention has as objective the stabilization of a fluoroether compound against degradation by acid substances. The stabilizers proposed are selected among propylene glycol, polyethylene glycol, hexylene glycol, 1,3-butylene glycol and a saturated cyclic alcohol preferably menthol and are used for preparing stable pharmaceutical compositions of a fluoroether compound. Method for stabilizing a fluoroether compound and use of stabilizers agents for precluding the degradation of a fluoroether are also described.

Abstract: The present invention describes ternary and quaternary eutectic mixtures composed by active local anesthetic substances. These eutectic mixtures possess melting point inferior to 20° C. and consist of homogeneous liquid useful in the preparation o pharmaceutical compositions for topical anesthesia or analgesia of tissues as skin or mucous.

Abstract: The present invention describes a new method for the separation of bupivacaine enantiomers consisting in a continuous separation process performed without heating, by the selective precipitation of their diastereomeric salts with tartaric acid. This heatless process avoids the degradation of the reagents granting a continuous process feature to the procedure. Another embodiment of the present invention is related to the enantiomeric manipulation of bupivacaine enantiomers in order to obtain pharmaceutical compositions presenting several enantiomeric excess of levobupivacaine to quantify and determinate the role of the dextrobupivacaine on its anesthetic and cardiotoxic effects. These enantiomeric manipulated compositions showed to present an expressive improvement on its anesthetic properties that had shown to be similar to racemic bupivacaine presenting a cardiotoxic profile similar to enantiomeric pure levobupivacaine.

Abstract: The present invention describes a new one ritonavir analogous compound that presents significantly superior activity in inhibition of HIV protease. There are also described the usage of the ritonavir analogous compound of the present invention or salt, ester or prodrug thereof as well as the usage of the compound and its pharmaceutical compositions in medicine, particularly, in the treatment of HIV infection, by itself or in combination with others anti-HIV drugs.

Abstract: The present invention describes ternary and quaternary eutectic mixtures composed by active local anesthetic substances. These eutectic mixtures possess melting point inferior to 2O° C. and consist of homogeneous liquid useful in the preparation o pharmaceutical compositions for topical anesthesia or analgesia of tissues as skin or mucous.
